Open Question: STATISTICS...CHI SQUARE PROBLEM please?

Can you please solve and explain how to get the expected frequency of this question? please please... An advertising executive in a large cosmetic firm knows that men purchase 89 percent of all perfume sold in the U.S. market. Her company is about to release a new perfume and she must determine whether certain names are more appealing to male customers than other names. Therefore, she conducts the following study. She manufactures a perfume that has a pleasant, but nondistinctive scent. She then puts this perfume in four identical bottles but puts a different name on each bottle label. She randomly selects 100 men from a shopping mall and after letting them smell each bottle, asks them to select the perfume that they would most likely buy. She obtains the following distribution. Name Number of Men Selecting Glory Daze 12 Seduction 33 Morning Mist 28 Compelling 20 Lamonah 7 A. Why is the chi-square the appropriate statistic to use for this analysis? B. What is the critical value for this problem if the significance level is set at .05? C. What is the chi-square value? Is it significant? D. What should this executive advise her company to do when they name the new perfume? Why? E. If you were involved in this research and could do the study again, what other variables would you include in a multiple sample analysis? more

Voting Question: Under counted black population in usa cities?

African-Americans historically undercounted in the U.S. census. Why and what's at stake? Now, a push to make sure it doesn't happen in 2010.BLITZER: It only happens once a decade. And the start of the next U.S. census is now less than two months away. But there's growing concern some segments of the American population won't by counted accurately. That would be African-Americans.Black Americans are losing out on important goods and services because they are undercounted in the U.S. Census, say several civil rights groups and Black leaders who want the government to spend more to encourage African-American participation in the 10-year count.From left, Rev. Al Sharpton, National Urban League Chief Executive Officer Marc Morial, and Rev. Jesse Jackson, take part in a news conference in Washington, Wednesday, Dec. 16, 2009, to discuss undercounting of blacks in the census. The National Urban League and the NAACP, joined by the Revs. Jesse Jackson and Al Sharpton, are urging U.S. Commerce Secretary Gary Locke to step up advertising and outreach efforts in such largely Black areas as Newark, N.J.; Oakland, Calif.; parts of Mississippi; and other places where African Americans are hardest to count and tend to distrust the government."The undercount of Blacks in the last count and the over-count of Whites by 1 percent is not just a Washington statistic," Sharpton said at a news briefing after the meeting. "It manifests itself in goods and services that cost us. …We want what is ours."Given high African-American incarceration rates – and the fact that inmates are often shipped to faraway, largely White communities to serve their time – Black leaders would also like the government to count prisoners as residents of the cities in which they previously lived, rather than in the places where prisons are located.There are a lot more things that have to be done for us to say that we are confident that this plan can address the historic undercount in this nation," said Marc Morial, president of the National Urban League and chair of the 2010 Census Advisory Committee.Locke said that his department would reevaluate how it allocates its $300 million communications campaign."African Americans and other minority communities have been consistently undercounted in past censuses so we're grateful to the respected leaders we met with for their commitment toachieving an accurate count," Locke said in a statement.The population figures, gathered every 10 years our population never had stop growing, it have been undercounted since alot of african american dont trust government they show not to partcapect in census those cities that black are higher never lose a black population many of them that live in city that have high black population like dc,Atlanta,New Orleans,Chicago many of them have been undercounted their proof that black populaton have been undercounted last 10 years the new data come out it will show you that our population is growing still percent is alot higher,we have a large community so it hard to count a bigger black population where census working wont go into those area cause they scar they going to get shot now they allowing to have black worker to go into those community so we wont go undercounted.if you want to find out your here the web site http://www.bet.com/News/National_Black_Leaders_Want_More_Accurate_Count.htm more

Resolved Question: Do you think this is false/misleading advertising?

I received a flyer for hair extensions in my mailbox that claimed that "95% of men prefer women with long beautiful hair" (it also pictured a scantily clad woman caressing herself with her hair covering her breasts) It didn't name a source for the statistic which I thought was interesting so I emailed the company to ask where they gained that information. She said they conducted a survey amongst 1000 people who were either clients or friends/family of clients & that is where they configured that statistic. I find this to be highly irresponsible as the flyer does not indicate any of this, it seems to represent the majority of the male population when only a small survey was conducted amongst a biased group of people. Do you think this is false advertising? I think they should have least disclosed the information of the survey on their flyer if they're going to use that information.I just thought it was misleading & aimed at people with low self esteem. My poor landlady lives upstairs & she has been through chemotherapy & has no hair now. I felt really bad she would have got one in her letterbox too. more

Resolved Question: Proability: Help asap please!!!!!?

I have been trying for the past couple of hours to figure out these problems & they're still unresolved. My homeworks due Friday please help!!! thanks :) 1. Suppose Jim is taking a multiple choice test and the probability that he answers any question correctly is 0.70, and that answers to different questions are independent. a) Jim is taking a test with 100 questions. Let X denote the number of questions Jim answers correctly. What is the distribution of X? b) What is the probability that Jim gets a 95% or higher on this test? Show your work. c) Use the Normal approximation to estimate the probability that Jim scores below a 65%. 2. At a gas station, 40% of the customers pump regular gas, 35% pump midgrade, and 25% pump premium gas. Of those who pump regular, 30% pay at least $20. Of those who pump midgrade, 50% pay at least $20. And of those who pump premium, 60% pay at least $20 (I would suggest labeling each event with some letter and then writing out what you're given in the probability notation presented in class). a) What is the probability that the next customer pays at least $20? b) What percent of customers who pay at least $20 pump premium gas? (Hint: write this out as a conditional probability and use your answer from part a). 3. The mean monthly rent for a random sample of 10 apartments advertised in the local newspaper is $640. Assume that the standard deviation is $90. Find a 95% confidence interval for the mean monthly rent in this area. Be sure to include an interpretation of your interval. 4. The SSHA is a psychological test that measures the motivation, attitude towards school, and study habits of students. Scores range from 0 to 200. The mean score for U.S. college students is about 115, and the standard deviation is about 30. A teacher who suspects that older students have better attitudes toward school gives the SSHA to 25 students who are at least 30 years old. Their mean score is x = 133.2. Assuming the standard deviation for older students is s = 30, test the claim that older students have a better attitude toward school at the a = .05 level of significance. That is, carry out the following test: H0: μ = 115 Ha: μ > 115 Make sure and report your test statistic, p-value, rejection decision, and conclusion. more

Resolved Question: The cause of decline in faith in God....Your Job? (Re-posted by request)?

The cause of decline in faith in God....Your Job? When mankind's brain first evolved to some semblance of intelligence, what we did with it was learn how to make stuff. We learned how to make tools, and to use those tools to create useful things, buildings, ploughs for agriculture, and libraries to store and share the collective knowledge (Eventually). Given that mankind were all builders and farmers...creators of things, it is of little wonder that when trying to make sense of "Creation", everyone truly believed that to create something, there must be a creator. When the early builders decided to build a town, the first thing they built, before a bakery, before a house, before all....was a church, a place to recognise what they saw as the best maker of stuff ever heard of, this is why churches are the oldest buildings in any given settlement. Most people these days, and for the last 3 generations really, have careers or jobs that produce.....nothing. How many people work in call centres, with no product at the end of their working days, except for the movement of money, from one place to another? How many in marketing and advertising, selling "Airtime" or "Space" with no tangible results, except the rise in sales of a given product, generally a product that is not essential to your life, because such products need no advertisment, and again, the shift in money. How many in banking....where money is quite literally created from nothing, and sold to our governments with attached debt, that our children's children will be paying off...with no tangible beneficial....solid product at the end? Is it all that hard to understand, that when it comes to faith, people have none....not in a God, not in each other, not in a society which produces nothing but greed and the promotion of self above all?

Would it be all that hard to see the only explanation of creation...was a creator...a God....the best damn builder of stuff in all of time? Peoples lives these days are all about a number on a balance sheet...why should they see God as anything different....a social security number....a statistic....something requiring quantification.

Resolved Question: How is my english essay? Please give feedback.?

Advertising Encourages Youth to Embrace Negative Gender Stereotypes The media today displays many aspects of the human physique in negative ways. It is quite apparent that youth currently are being affected harmfully both mentally and physically due to the fact that advertisements are bombarding them with negative gender stereotypes. Encouraging students to embrace these negative qualities gives them the obsession to find that ideal body type to fit that advertisement description with any means possible. Secondly, this makes youth feel that embracing the negative stereotypes, even if it goes against their own morals, allows them a sense of fitting in with this society. For these reasons, advertising in today’s materialistic world promotes youth to embrace gender stereotypes and consequently gives them the obsession for the advertiser’s ideal body type and making it seem it is the only way to co-exist with the fad. With youth at the tender age where their self-esteem is fragile, the advertisements give them the sense that it is the only way to fit in and become normal, or cool. Youth are very impressionable when it comes to the media. A quote from the article The Price of Happiness states, “Advertising at its best is making people feel that without their product, you’re a loser.” Some products that advertised may seem out of the question with some youth, but if it appeals to their emotions then they buy into what they are trying to sell. From this, they feel a sense of self-confidence and belonging. Overall, this puts a lot of pressure on youth through their peers and society itself to show the change into the people they are not. If teenagers are not wearing the latest clothing line, as everyone does, they are seen as social outcasts and it forces them to follow advertisements as if it were vital. The American Psychological Association released a report that concluded that the sexualization of young girls causes them stress with mental and emotional breakdowns. It increases in their minds because not only do they think about it but also rather, it is repeatedly being shown in the media at any given time. It was inevitable that something would result from this sort of pressure. In schools and societies across the country, it is apparent that teenagers are being segregated for the image that is not the total Barbie Doll look. As a result, teenagers tend to take on the role as clones to look and act like everyone else to avoid confrontation. For instance, within R.H. King many, many students are seen with Hollister, Abercrombie, or Aeropostale just because it looks “hot” to wear it. Many feel that you can share that type of relationship with a girl/guy in an intimate manner as they do in the advertisement. Consequently, everyone is similar and unoriginal and stereotypes break loose. From that, it is evident that they act quite differently to fit that advertisement which expresses the seriousness and dominance in men, and vulnerability and submissive attitude that women portray. From an advertisement promoting Dolce and Gabbana, it gives the perception that all males are dominant and strong. The woman on the other hand, is quite submissive and shows her lack of self-confidence. This gives youth the impression that acting as they do in advertisements allows them to fit the category of being a man or a woman. Moreover, not only does it affect youth mentally, but physically gives youth an obsession for that ideal body type. There are many different methods that youth try to attain the ideal body all affecting themselves harmfully. Health Canada has a statistic, which states that 1 in 2 girls and 1 in 5 boys in grade 10 either were on a diet or wanted to lose weight. One method to achieve that six pack or bean pole body shape is by going on a yo-yo diet. A yo-yo diet causes a person to lose weight, but in the end, the weight comes back and sometimes increases from before. Many teenagers believe that eating nothing will give you that self-conscious belief that you are thin. The Canadian Medical Association Journal in 2001 published an article that stated 27% of girls aged 12 – 18 have a problematic food and weight behavior. Secondly, from News Week 1 of 10 males have an eating disorder. This proves that being bombarded with ads, males and females take it so personally that they are willing to harm their bodies to achieve that status. Nobody seems to care for what others do to achieve perfection because they can see themselves doing the same thing. As a result, youth are given the impression that trying to accomplish the perfect body type is a good thing. This leads youth to the sensitivity of their body image. It is apparent that a huge portion of youth feels that their body is satisfactory. This may cause them to have poor self-esteem. Comparisons start to occur with youth to who looks thinner or more muscular which also influences their mind. Body image is displayed in advertisements, much of the more

Resolved Question: Linear Regression in Excel?

Could anyone help out with this set of information I. The desirability of any financial investment depends heavily (though not exclusively) on its risk. Many stockbrokers, financial consultants and academicians use a model known as the “beta model” to identify the riskiness of securities. For example, Merrill Lynch provides the beta risk index as a regular service to its customers. The beta coefficient of a security is measured by the simple regression technique. The dependent Variable is the rate of return of the security(Y) and the independent variable is the rate of return on a portfolio of all the securities traded in the market(X). Using the past rates of return we can run the following simple regression: SRR=b0 +b1MRR + e with SRR :stock rate of return and MRR market rate of return STOCK RATE OF RETURN :SRR YMARKET RATE OF RETURN :MRR X 2.0 -10.0 18.0 9.0 12.0 -1.0 -12.0 2.0 1.0 -5.0 12.0 5.0 7.0 0.0 -6.0 2.0 a) Calculate b0 aund b1 b) Interpret the estimated regression line and the Coefficient of Determination c) Test the null hypothesis H0:B1=0 versus H1 :B10 AT 5% level of significance. d) A investor is willing to invest in that stock only if the beta is 1.5 How would you do and what would you advise him or her?

The statistic 'men think about sex every three seconds' - probably because every three seconds you walk past a billboard or magazine with some scantily-clad model trying to appeal to your 'secondary brain' (primary, in some cases).

Resolved Question: whats your opinion on this essay?

Sexism Also Effects Men Many feminist fight against sexism but there focus is usually on women, failing to recognize that we are not the only ones effected by sexism. In the article Sexism in Comics the author, Robert Tidewall a feminist says, “Sexism can be found in pretty much any context, even when the writer or artist is a woman” Clearly he believes that women can be sexist towards women.” Which I completely agree with, but by saying the words “even women can be found sexist” gave me the feeling that this author believes that only women are affected by sexism. While I believe that sexism affect both men and women. There are many cartoons and television shows that portray the male gender as being dumb, fat and lazy. Such as animated American sitcoms like The Simpson’s and Family guy. When we see these shows we continue to watch them and laugh while doing so we fail to notice these shows use sexism that’s aimed towards men. When we find shows that are sexist toward women we usually get upset or offended but when shows are sexist towards men most of the time we don’t even notice them. I believe we notice sexism when it’s aimed towards women because we have people that stand up for women’s rights opening our eyes to this type negative behavior. On the other hand men’s rights are not a focus in our society at this point of time. So we unintentionally ignore the negative behavior aimed towards men. In the article “Tolerance in the news” the author Michael Abernathy, provides his readers a list of sexist comments about men found in both commercials and television shows. He talks about how television shows create negative stereotypes of men and the effect it has on young men. He goes on to mention a statistic provided by "Gender Issues in Advertising Language," that states “Young men learn that they are expected to screw up, that women will have the brains to their brawn, and that childcare is over their heads.” Clearly the author believes that by watching these commercials and television ads young men receive a negative perception of the male role. I agree with him because as young people we intake much of what we see and apply it to our lives. For an example my boyfriend was mislead by these sexist television shows thinking “I can’t take care of babies I’m a guy.” When in fact he’s a great father that is often giving me advice on how to care for babies. This goes to show that just like women men are also affected by sexism and it should be considered wrong towards both genders. In the article “Cultural Insensitivity to Sexist Language Toward Men” the authors did a study on the use of sexist language towards both men and women. They presented 60 undergraduates with the question “How many of you have followed through with those New Year's resolutions: Started that diet, gotten rid of your (boyfriend/girlfriend/dating partner), and begun your exercise program?" They then stated “The results of this study show that subjects were not sensitive to sexism in language toward men but that they were sensitive to sexist language toward women” The statement “gotten rid of your girlfriend”, was considered sexist. While the Statement “gotten rid of you boyfriend” wasn’t. This study shows that we notice things that are sexist towards women but fail to recognize when things are sexist towards men. As you can see sexism effect both genders and we can see this by watching our favorite television shows. We need to be aware of sexism and the effects it has on both men and women. Is not that people approve of male sexism it’s just they unaware that there even seeing it. As we stand against it and inform people of the problem they will begin to notice this negative behavior in our society and changes will begin to be made. Work Cited 1.Abernathy, Michael.

Resolved Question: This is my essay which I've just completed. Please correct my faults if you can. Thank so much !?

This is my essay which I've just completed. Please correct my faults if you can and give me your opinion. Thank so much ! TOPIC: HOW MANY TYPES OF ADVERTISING ARE THERE? PRESENT THE FEATURES AND EXAMPLES OF EACH TYPE. ANALYZE THE APPROPRIATENESS OF THEM. Nowadays, almost companies can’t lack advertising to introduce their products or services to market. There are many types of advertising. Each type has different role and appropriateness. So, this essay will focus on three types in three paragraphs. Introducing about print advertising in the first paragraph; and then, introducing mass media advertising in the second paragraph; and finally, introducing outdoor advertising in the third paragraph. Today, advertising products via print media is a common practice. The print media include all newspapers, newsletters, magazines, booklets, pamphlets, and other printed publications. The role of print advertising is to offers basic information about the company, their products or services to the selected audiences. Most print media are local. Magazines, on the other hand, have always been national, although there is a trend today toward localization and specialization. There are a huge amount newspapers and magazines are published everyday. But only some types tend to a particular group people. For examples, sporty newspapers are written for men, teenage magazines for teenagers, etc. Therefore, select the right type of newspapers or magazines is important decision of the company, which may reach larger selected audiences. According to a statistic, in Vietnam, at present, there are about 600 newspapers and magazines. Almost companies, which are operating in Vietnam, are advertising via print media; for examples, Vinamilk, FPT, Honda, etc. Mass media advertising is popular most and impact in people’s awareness of the companies and their products. This type includes TV, radio and internet. Mass media advertising is more than simply persuasive messages. Through text and through images, the ad conveys values and beliefs, and these have meanings for those who read, listen or watch them. In this type, cost is the main obstacle for companies which want to advertise on TV. Moreover, just as print ad, mass media ad also has many channels tend to many different objects. Consequently, if the company advertises with reasonable duration and right channel, the company will not waste more money and their advertising still effective. Due to the great role of mass media in the life, nowadays, there are many companies use mass media for their main publicity. For instance, Unilever present their products as OMO and Comfort, P&G with Tide and Downy, etc. Outdoor advertising, one of the oldest and most enduring forms of advertising, is advertising on signs that are located outdoors in public places. This form includes billboards, trade fairs, sporting evens, etc. Outdoor advertising captures the viewer's attention 24 hours a day. True, it has limited coverage. But a well-planned outdoor campaign can effectively cover most major markets. The main features of this type are brevity of the message and cannot target customer. So, the message usually is slogan of the company, such as Canon Corporation with the slogan is “Delighting you always” or Toyota with sentence “Moving forward”, etc. In short, using which types and using on which time is important decision of the company. In my opinion, with carefully choosing, the company can get what they need from all the variable advertisements more

Then they are shown a series of candidate ads, and are again asked to rate the candidate from 0-100. The mean of the differences is found to be 14.66 and the standard deviation is 5.21. The sample size is 15. assume α=.05. A. what are the null and alternate hypotheses? B. Calculate the observed value of the test statistic. C. What is the critical value? D. State Conclusion. Thank you to anyone who can help! more

Resolved Question: Statistics help please?? null hypothesis?? alternative hypothesis?

Our company's new "Lite" yogurt is supposed to contain only 1.5 grams of fat. The FDA monitors these advertising claims for accuracy. If they can prove, at the 10% significance level that our product contains more fat than advertised, then we will be subject to fines and product recall. A sample of 90 packages yielded an average of 1.54 grams of fat, with a standard deviation of 0.16. Perform the appropriate hypothesis test to see if our product violates FDA advertising standards. Write the appropriate null and alternative hypotheses. H0: _______________ H1: _______________ Write the rejection rule for the null hypothesis. Calculate the appropriate test statistic. Write a conclusion. Do we reject or fail to reject the null hypothesis? What do we believe about the fat content of the yogurt? Find the p-value. more

please help with steps It has been claimed by those who have developed the SAT that special courses for this exam have no effect on the overall scores. Suppose that you are interested in this question, and specifically would like to determine if such a course that is advertised locally has an effect, good or bad, on SAT scores. You arrange to have a random sample of 100 students take this course before the SAT is given. Suppose that the average score for all students who took the exam at that time was 440 on the verbal portion and 425 on the quantitative portion. Also, suppose that the sample of 100 students who took the course had a mean verbal score of 452 with a s.d. of 110, and a mean quantitative score of 448 with a s.d. of 80. Did the course have an effect on the mean verbal SAT? Did the course have an effect on the mean quantitative SAT? Use 5% level of significance. Construct 95% confidence intervals for the mean verbal SAT score and for the mean quantitative SAT score more
